Here's what people are saying about us

"Dr. Sharma was able to diagnose a rare liver problem and a friend of mine. He flew back and forth between Houston and San Antonio to help with his patient. Which is way beyond the call of duty. He also helped organize a team to deal with this rare condition. And then he would fly back home to San Antonio. Those of you that live in San Antonio should be very grateful you have this doctor in your area."
"I would like to give a sincere Shout Out! to Dr. Desh Sharma who assisted me on Friday when I was having severe abdominal pain and couldn't get an appointment to see my GI Doctor. Dr Sharma did a quick examination and sent me for a CT Scan. He went above and beyond by calling me that night to give me the results and prescribing medications for me..."
"Dr. Sharma, I am so thankful you took my case. You made me a promise that you would not stop looking until you found out what was wrong with me & you kept your promise. I am so thankful & honored that you became my doctor & turned my life & body around. I appreciate you so much & very thankful for all you did for me."
